WebIn magnetohydrodynamics (MHD), shocks and discontinuities are transition layers where properties of a plasma change from one equilibrium state to another. The relation between the plasma properties on both sides of a shock or a discontinuity can be obtained from the conservative form of the MHD equations, assuming conservation of mass, momentum ... Web26 Feb 2024 · The Hugoniot curve is the locus of final states achieved with a single shock from a given set of initial conditions (note that it is not the thermodynamic path followed during shock compression). Each shock experiment thus determines a single datum on the Hugoniot curve . An important consequence of Eqs. Webin Fig. 2 is the tangent to the Hugoniot curve and the point of contact shows the C-J state. Next, the shock Hugoniot(S-H) curve is similarly cal- culated from the initial condition, IC. Then, the inter- section of this curve with the Rayleigh line, s, is calcu- lated in order to determine the condition of the leading shock-wave. mohn surgery with skin graft
